Optimization of reluctance motor with printed rotor

A novel way of optimizing a reluctance motor with rotor manufactured by 3D printing technology is presented. The optimization algorithms must take into account the tolerances of its production that are generally higher compared with classical processing, which requires a high level of&#...

Minimum infinity norm-based PWM for three-phase four-leg converters

Control of four-leg voltage-source converters operating on three-phase systems traditionally faces the problem of transformation from a four-degrees of freedom (DOF) modulation space to a three-DOF output-voltage space. Contemporary, it is highly desirable to minimize the leg voltage, and consequently...

Finite control set model predictive control of static compensator

Static Var Compensators (SVC) are related to improve quality of electrical energy in power grids. There are described two topologies of the static var compensator in the paper. First of them is a star/Y-connected topology and the second one is a delta/D-connected topology....
